BOOT AND SHOE HEELING MACHINE.

SPECIFICATION forming part of Letters-1 Patent No. 252,105, dated January 10, 1882.

Application tiled August 16, 1881. (No model.)

To all whom it may concern.'

Beit known that I, WILLIAM J. HEFFER- NAN, of Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Boot and Shoe Heeling Machines, of which the `following is a specification.

This invention relates to heeling-machines employing nail-holders arranged in gangs and corresponding gangs of drivers supported by a rotary head or frame adapted to bring the gangs successively over the boot or shoe supporting last under the driver-operating incollanism. Y

The invention consists in certain improvements which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure l representsa side elevation of a machine embodying my invention. Fig. 2 represents a front elevation of the same. Fig. 3 represents a perspective view of a portion. Fig. 4 represents a section on line `m m, Fig. 2. Figs. 5 and 6 represent respectively` top and side views ot' one of the sections on line ze, Fig. 5, the jaws being in different positions. Figs 9 and l0 represent end Views ot' the nail-holder, the jaws being :in the positions shown in Figs. 7 and 8. Fig. ll represents a section on line x x', Fig. 7. Fig. 1 2 represents a bottom view of one of the nail-holders, showing a spring for inclining the nail. Fig. 13 represents a section on line z a', Fig. l2. Fig.`14t represents a bottom view of .a heel in which the nails have been driven.

The same letters of reference indicate the same parts in all the figures.

into and out of theiroperative positions. Each gang of nail-holders c is supported between two vertical guides, ff, 'rigidly attached to the head b, and each gang of drivers is supported by a plate, g, which is adapted to slide on the- Figs. 7 andS represent` guides ff, the driver-bar. e of each gangof drivers projecting above the head b, and being provided with a spring, l1., which is adapted to raise the gang of drivers above thel gan g ot' nail-holders, asshown at the right hand of' Fig. l, so that the attendant can readilyinsert the nails into the rear gang of holders, the latter being unobstructed by the drivers.

t' represents an arm rigidly attached to the pillar a, and provided at its outer end with upwardly-projecting bearings jj, in whichis jonrnaled a shaft, lf, carrying a cam, l, anda clutch-pulley, m, for the belt that rotates said shaft. The cam I, which depresses the diiverbaraud forces the nailsthrough the nailiholders, bears upon an intermediate drivenbar, o, resting upon the upper end of the driver-har vproper and held in yielding contact with the cam by a spring, p.

@representsan inclined surface formed on the arm i at one side of the `bar o. face is adapted to depress each driver-bar e when it is moved `toward `its operative position by the rotation of the head b, and thusdepress the drivers d nearly to the nail-holders, so that Sa id sur-4 the downward movement of the drivers by the cam l does not require lto be of such extent as it would without the surface q, and the nails are therefore more rapidly driven. The holder or frame of eachgang of nail-holders is provided wirh a rearwardly-extending arm, s, which has a spring holt or catch, s', adapted to engage automatically with an arm, t, rigidly attached to the pillar a, and lock the head able bolts and provided with diverging slots B,in which the blocks u are placed, said blocks being movable in the slots, so that they can be adjusted to hold nails for heels of different sizes. Each block is reduced in size where it enters the slots, and is threaded at its upper end and provided with a jam-nut, C, adapted to secure the block to its frame.

Thejaws w w are arranged to press inwardly against the sides of the nail, and one of said jaws is beveled at the upper portion of its inner edge, 'as shown in Fig. l1, so that in case the nail is inserted diagonally, as shown in the last-named figure, the beveled edge will partially turn the nail until its wider sides are parallel with the proximate edges of the lower portions of thejaws, as shown in Fig. 10. The nails are thus caused always to maintain the same relation to thejaws, so tllat by a proper arrangement of the jaws all the nails will be driven with their wider transverse sections substantially at right angles with the surface of the heel, as shown in Fig. 14, and will therefore be prevented from being turned outwardly -where they are clinched.

I prefer to provide each block with a springjaw, D, arranged to bear against one side ot the point ot' the nail and give the latter an inclination corresponding somewhat to the inclination of the heel, as shown in Figs. 12 and 13.

Each gang of drivers d is mounted ona plate, E, which is provided with -a dovetail groove receiving a corresponding tongue on the plate g, which is rigidly attached to the driver-bar h. The plate E, with its drivers, is therefore adapted to be removed from the driver-bar, so

that different-sized gangs can be employed. I

do not limit myself, however, to the tongue and groove, as any suitable means for detachably connecting the drivers to the driver-bar may be employed without departing from the spirit of my invention.

The boot or shoe holding last G is supported on a vertical screw-shalt, H, which is journaled in a standard, I, and rotated by bevelvgears J K and a hand-wheel, L, to raise and lower the last, which is prevented from rotating by a fixed guide, L', projectinginto a socket, M, in the last, as shown in Fig. 4. rlhe operator is thus enabled to raise the last and press the heel against the gang of nail-holders, as shown in Fig. 1.

O represents a toe-piece mounted on a bar, P, which is movable in and out of a socket, P', in the last by means of a rack, B, and pinion Q. The toe-piece can therefore be moved toward or from the body ofthe last to adapt the f same to different lengths of bootsl and shoes.

gang are being inserted into the heel.

Having thus described my invention, I claim- 1. In a heeling-machine, the combination of a gang of nail-holders supported by a rotary frame or head, a gang of drivers adapted to move vertically in guides above said nail-holders, and normally elevated above the nail-hold ers by a spring or its equivalent, a cam to depress the driver-bar and force the driversinto the nail-holders, and a fixed inclined surface adapted to partially depress the driver-bar before it is acted on by the cam, as and for the purpose specified.

2. In a heeling-machine, the combination of a series of gangs of nail-holders supported by a rotary frame or head, a last to support the boot or shoe, a series of gangs lof drivers corresponding with the gangs of nail-holders and elevated above the same by springs, so that normally the nail-holders will be unobstructed by the drivers, a fixed inclined surface adapted to partially depress the driver-bar ot' each series before said bar comes into operative-position over the last, and a cani adapted to further depress the driver-bar when the same comes to its operative position, as set forth.

3. In a heeling-machine,the combination of a gangofnail-holders with aframe for said holders, constructed to permit of the adjustment of each of said holders radially in and out, and clamping devices for securing the holders in adjusted position,whereby the holders areadapted to be set for placing the nails uniformly in heels of different sizes, substantially as described.

4. The combination of the gang holding frame composed of the connected top and botsaid holder and arranged to bear against one side of the point of the nails, so as to give the nail an inclination corresponding somewhat to the inclination of the outside ofthe heel, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 9th day of August, A. D. 1881.
